Using Parks and Recreation Providers to Enhance Obesity Treatment: A Randomized Controlled Trial.

OBJECTIVE: Intensive health behavior and lifestyle treatment (IHBLT) is recommended for children aged 6-18 years with obesity. The objective was to evaluate the effectiveness of Fit Together, a health care and parks and recreation partnership to deliver IHBLT. METHODS: A randomized controlled trial was conducted from 2018 to 2021. Youths (aged 5-17 years) with obesity were recruited from primary care clinics and randomized to a waitlist control or Fit Together (ie, clinical obesity care plus group-based lifestyle sessions at a local recreation center). Primary outcomes, child body mass index relative to the 95th percentile (BMIp95) and submaximal heart rate, were collected at baseline and 6 months. Generalized estimating equation models were used to assess changes in primary outcomes for those affected and not affected by COVID-19 study disruptions. RESULTS: Participants (n = 255) had a mean (SD) age of 10.0 (3.0) years, were 39% Hispanic, and were 38% non-Hispanic Black. Intervention youths not affected by COVID-19 disruptions experienced a significant decrease in BMIp95 (β = -3.05; 95% confidence interval [CI], -5.08 to -1.01) compared with controls. There was no difference in BMIp95 between intervention and control youths affected by COVID-19 disruptions (β = -3.25; 95% CI, -7.98 to 1.48). For the entire cohort, intervention youths had a significant decrease in BMIp95 compared with control youths (β = -3.32; 95% CI, -5.69 to -0.96). Submaximal heart rate was only available for the nondisrupted group, but there was no difference between intervention and control youths (β = -7.18; 95% CI, -16.12 to 1.76). CONCLUSION: Effective child obesity treatment can be implemented in local communities through a partnership between clinical practices and parks and recreation providers. Future research will explore this model in combination with newer, more effective obesity treatments.
